Title: Magnetic head and its manufacture
Inventor: TOYOSHIMA FUMITOSHI
IPC: G11B5/127
Filed: 1986-03-24
Abstract: PURPOSE:To prevent deterioration in an S/N in a recording/reproducing time, and to obtain a recording/reproduction with high accuracy, by giving an azimuth against a magnetic gap on a boundary plane between a magnetic body in which the magnetic gap is formed, and a magnetic material that forms a core. CONSTITUTION:First of all, 'Sendust(R)' layers 17a and 17b are formed on core half body blocks 16a and 16b, and the planes of them are polished making angles of psi, and the half body 16b is joined to the half body 16a by forming a nonmagnetic material 19 having a gap thickness, and track grooves 21 are processed, and a head whose gap plane is inclined in an angle of theta, can be obtained by slicing the grooves with the angle of theta against a reference plane. Since the layers 17a and 17b are inclined in the angle of psi, the head having the azimuth of theta can be obtained by polishing the gap plane in the direction of a track width. Therefore, the deterioration in the S/N is not generated in the recording/reproducing time, even when a spurious gap function is generated at the boundary plane, and since a gap part is put in a highly saturated density state, the recording/reproduction with high density can be performed.

Title: Lamp life detecting circuit
Inventor: KUBOTA SATOSHI
IPC: H05B41/00
Filed: 1981-04-30
Abstract: PURPOSE:To detect the end of life of a lamp and to reduce the power consumption, by detecting the voltage generated across a current limiting element and counting the voltage in a digital way to detect the change of the voltage. CONSTITUTION:In the normal state, a lamp 97 glows after the application of a power supply 99, and the collector voltage of a transistor 18 of a voltage detecting circuit 1 kept at H level. A counter 2 does not count plural numbers, and a lift detecting circuit 3 delivers nothing with no working of a relay 5. Thus the lamp 97 is kept glowing. In case the lamp 97 is at the end of its life, the collector voltage of the transistor 18 repeats L and H levels. At the same time, the counter 2 counts up its value. When the count value of the counter 2 reaches a prescribed level, the circuit 3 detects this. Then the signal is fed to a relay 5 to cut off the circuit 3. In such a way, the useless consumption of electric power can be previously prevented in the half-wave glowing mode.
